Patented Dec. 29, 1931 PATENT; OFFICE ANTOINE L. ALAJ', OF CHICAGO, ILLINOIS ELECTRIC PEBGOLATOB Application filed January 17, 1981. Serial No. 509,484.

This invention relates to an electric percolator and has for its prlmary ob ect to provide, in a manner as hereinafter set forth,

a percolator by means of which coifee may be prepared having a pleasant aroma and further having a rich flavor entirely free from caffeine, tannic acid, and other b1t ter elements.

A further object of the invention is to provide a percolator of the character aforesaid, by means of which cofiee maybe prepared without boiling the coffee solution and without subjecting the solution to contact pith the grounds used in preparing the cof- A further object of the invention is to provide a percolator of the character aforesaid which is inexpensive to manufacture, simple to use, and which is also applicable for preparing tea.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more particularly described and as illustrated in the accompanying drawings wherein is shown an embodiment of the invention, but it is to be understood that the description and drawings are to be taken as illustrative and that the invention is intended to be limited only by the scope of the claims hereunto appended.

In the accompanying drawings in which like numerals are employed to designate like parts throughout the several views:

Figurel is an elevation of a percolator in accordance with this invention.

Figure 2 is an enlarged sectional elevation thereof.

Figure 3 is an elevation of a modified form of percolator in accordance with this invention.

Figure 4 is a reduced bottom plan of the spray element through which hot water is ejected onto the coffee grounds.

Referring to the drawings in detail, the numeral 1 indicates a receptacle for containing the cofiee solution, such receptacle preferably being of cylindrical formation, and preferably being mounted on a suitable base 2. The receptacle 1 is provided with a pair of handle members 3 in order that the percolator may be conveniently handled and is further provided with a spigot 4 through which the solution may be drawn when it is desired to use the same. The receptacle 1 preferably is formed with an open upper end with the wall of the percolator being rolled at its upper edge as indicated at 5. Disposed within the receptacle 1 is a perforated basket 6 for containing cofiee grounds 7, the basket 6 preferably being supported on a plurality of lugs 8 which extend from the inner face of the receptacle 1 and project beneath the rolled upper edge 8' of the basket 6.

Seated on the receptacle 1, and closing the upper end thereof, is a substantially cylindrical carrier 9 for a valve indicated generally at 10 and a heating element indicated generally at 11. The valve 10 includes a vertically disposed housing 12 having a reduced, externally threaded lower end 13 extending through an opening formed centrally of the bottom 14 of the carrier 9. The housing 12 is maintained in position with respect to the carrier 9 by means of a spray element 15 which is substantially in the shape of a shallow pan having its upper wall formed with a neck 15 threaded on the extension 13. The element 15 covers substantially the entire area 1 of the basket 6 and is formed in the bottom thereof with a plurality of openings 16 for a purpose to be hereinafter referred to. End portions of the housing 12 are formed with relatively large, aligned openings 17 and 18 which are in communication respectively with relatively small, vertically offset openings 19 and 20. Communication between the openings 19 and 20 is established by means of a horizontally disposed opening 21 arranged centrally of the housing 12. Formed with the housing is a horizontally disposed, tubular projection 22, the inner wall of which is in alignment with the wall of the opening 21. Extending through theprojection 22, and threadedly engaged with an inner end portion thereof, is a valve stem 23 by means of which the opening 20 may be closed tothe opening 19. The housing 12 is provided with a reduced, externally threaded upper end portion 24 whereby the housing is provided with an external shoulder 25. Encircling the portion 24 and seating on the shoulder 25 is an annular supporting member 26 which is formed with an upwardly peripheral portion 27. Seated on the port-ion 27 is the heating element 11 which is of annular construction and which projects both inwardly and out- Wardly beyond the portion 27 The heating element 11 is provided with a pair of con,- ductors 28 and 29 which are connected with a plug element 30adapted for connection with an electrical lead in line 31.

Seated on the supporting member 26 and carrier 9 is a water container 32 which is a preferably of cylindrical construction and which is formed with a suitable cover 33. The

' tion of the reduced extension 24 therethrough.

threaded on to the reduced extension 24, the" Encircling the portion 34, the bottom of the container is formed with an upwardly pro- 'ecting annular portion 35 into which the.

eating element 11 projects. The container 32'is held in position by means of a nut 36 water within the container being prevented from leaking out around the extension 24 by means of a suitable gasket 37 disposed beneath the nut 36.

The percolator illustrated in Figure 3 is the same in every respect as that illustrated in Figure 1 except for the modified shape of the coffee solution receptacle 38. The receptacle 38 is of less height and ofgreater diameter than the receptacle 1, and is provided with a spout 39 oppositely disposed with respect to a handle member 40.

In the use of a percolator in accordance with this invention, the basket 6 is filled or substantially filled with ground coffee, and the container 32 is filled or substantially filled with water. The heating element 11 is then connected through its plug 30 with a source of electrical supply, by means of which the is no heating of the contents of the receptacle 1, and that no portion of the ground coffee 7 invention as defined in the appended claims.

What I claim is .1. An electric percolator comprising, a coffee solution receptacle, a carrier member seated thereon, a valve housing carried b the carrier member and projecting throug the bottomthereof, a spray member secured to the valve housing and projecting into the receptacle, a water container seated on the carrier member and having said housing proecting through the bottom thereof, said valve ousing having end portions thereof formed with vertically offset, longitudinally extending openings, said valve housing further having a horizontally disposed opening for establishin communication between said vertically ofiset openings, a tubular extension projecting laterally from the valve housing and havin its inner wall in alignment with the wallo said horizontally disposed openings, a valve stem extending through said tubular projection for closing said vertically ofi'set openings to each other, means for supporting a supply of ground coffee beneath the spray member, and an electrical heating element seated on thecarrier member and engaging the bottom of the container for heating the water within the latter.

2. An electric percolator comprising, a coffee solution receptacle, a carrier member seated thereon, a valve housing carried b the carrier member and projecting through the bottom thereof,- a spray member secured to the valve housing and projecting into the receptacle, means for supporting a supply of ground coffee beneath the spray member, an annular supporting member seated on the valve housing and having an upwardly offset peripheral portion, an electrical heating element seated on said upwardly offset pein communication between said vertically offset openings, a tubular extension projecting laterall from the valve housing, a valve stem exten ing through said tubular extension and into said horizontally disposed opening for closing said vertically ofiset openingsto each other, means for supporting a sunply of ground coffee beneath the valve housing, and means for heating water within said container.

In testimony whereof, I aflix my signature hereto.
